TRACK-SANDIN G APPARATUS.

Patented J'an. 26, 1909.

Application led. July 28, 1908. Serial No. 445,704.

To all whom it may concern.'

Be it known that we, FREDERICK L. ROB- INSON and JOHN MCOABE, citizensof the United States, residing at Cheyenne, in the county of Laramie andState of lllyoming, have invented a new and useful Track-SandingApparatus, of which the following is a specification.

This invention relates to track sanding apparatus for locomotives andmore particuarly to Sanders of the type disclosed in Patent No. 844,618,dated February 19, 1907. In mechanisms of this character where sand canbe delivered in rear as well as in advance of the driving wheels, itwill be understood that the rear ander is seldom used, and then only inan emergency. As a consequence, sandbecomes packed therein, and thisparticular part of the apparatus is apt to become inoperative for thatreason.

One of the principal objects of the present invention is to constructthe mechanism so that fresh sand is constantly fed to both the rear andforward Sanders whenever the latter is used, thus avoiding the objectionnoted.

A further'and important object is to provide a simple form of air nozzlefrom which the sand is effectively excluded without interfering with thesupply of air, said nozzle moreover being of a character that willpermit its being cleansed without the necessity of dismantling the airconnection.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a side elevation of alocomotive with the apparatus in place thereon. Fig. 2 is a form inelevation on an enlarged scale of a portion of the mechanism. Fig. 3 isa longitudinal sectional view therethrough on an enlarged scale. Fig. 4is a detail sectional view on the line 4 4 of Fig. 3.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated, the locomotive, which is designated bythe reference numeral 5 is provided with the usual driving wheels 6 andwith a reservoir or sand box 7. From Vthis reservoir on each side, leadsa single sand conduit 8, the lower portion of which is in the form of acasing 9 having its bottom closed by a detachable plug 10. Leading fromone side of the upper portion of the casing 9 is a sand-conducting pipe1 1 that has its discharge end disposed in rear of one of the drivingwheels 6. Leading from the opposite side of the casing 9 and at a lowerpoint, is another sand-conducting pipe 12 that delivers in advance ofone of the driving wheels 6, as will be evident by reference to Fig. 1.Air or motive fluid supply pipes 13, extending from the cab of thelocomotive and provided in. said cab with any suitable controllingmeans, are connected to nozzles 14 and 15. rFliese pipes furthermorehave branches 16 extending over the locomotive to the sanding apparatuson the opposite side, as will be evident by reference to Fig. 1.

Each of the nozzles 14 and 15 comprises a tapered body 17 having` aportion threaded as shown at 18 into one side of the casing 9. Thus inthe present embodiment the nozzle 14 is located opposite to the inletend of the pipe 11 and in line therewith, while the n0z zle 15 isarranged opposite to and in line with the inlet end of the pipe 12. Jamnuts 19, threaded on to the nozzles, abut against the sides of thecasing to securely maintain the nozzles in position. It will be notedthat each nozzle is provided with a longitudinal bore 20 extendingentirely through 'the same and an inclined lateral supply port 21communicates with this bore between its ends. The pipes 13 are incommunication with the ports 21. Inasmuch as the inner ends 22 of thenozzles extend across the casing, enter the inlet ends of the pipes 11and 12, and are of less cross sectional area than said pipes, it will beevident that air supplied through these nozzles will be projectedlongitudinally into the inlet ends of said pipes, and, forming partialvacuums in the casing, will cause the sand to be drawn into the ipes anddelivered either in advance of or behind the wheels. The outer ends ofthe bores 20 are closed by plugs 23, and carried by the inner ends ofthese plugs are stems 24 that extend longitudinally through the bore,being of less cross sectional area than the same and spaced from thewalls of the bores. In the lateral ports 21 are turning valves 25 havingintersecting ports 26 and 27 of different diameters. These valves arefully covered by the prior patent, to which reference has already beenmade.

Particular attention is called to the fact that the pipe 12, whichconveys sand to a oint in advance pf the dri-vers., `is located owerthan the pipe 11. As already `stated. the Jforward sander is used ,muchmore than the rear sander, and it will'be evident that ,in

this construction all the sand, which is passed through said forwardsander, vor in vother words, through the .pipe 12, must pass through theupper .portion of the casing, and consequently past the rear sander 11.There is thereiore no chance of the sand becoming packed in the rearsander, and the latter is always ready tor use.

lt rwill be evident by reference to Fig. 3 that this structure is verysimple, and there are decided advantages for the particular' form ofnozzle employed, in the iirst place, the stem 24 excludes grains of sandfrom entering the nozzle, and the valve 25, being located above thebore, is completely protected from the dirt. However, should it becomenecessary to cleanse the bore, the plug 23 and stem 24 can be readilyremoved without dismantling the connection oi the pipe 13 with thenozzle.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention, will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size,shape, proportion, and minordetails of construction may be resorted to without departing from thespirit or sacrificingany ofthe advantages oi the invention.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is :i
